There is no affordable rentals in Brisbane for students or single parents, a new study has found.

The study, conducted by the Anglican Community Services Commission, found that just 3% of properties listed on the weekend of 11-12 April would be viable for people with a regular income. None of the listed properties would be available for students on Youth Allowance or a single parent.

The research suggests that Brisbane housing has become some of the most expensive in the world.
